Affordance-Based Individuation Of Junctions In Open Street Map, Simon Scheider, Jörg Possin
Affordance-Based Individuation Of Junctions In Open Street Map, Simon Scheider, Jörg Possin
Journal of Spatial Information Science
We propose an algorithm that can be used to identify automatically the subset of street segments of a road network map that corresponds to a junction. The main idea is to use turn-compliant locomotion affordances i.e. restricted patterns of supported movement in order to specify junctions independently of their data representation and in order to motivate tractable individuation and classification strategies. We argue that common approaches based solely on geometry or topology of the street segment graph are useful but insufficient proxies. They miss certain turn restrictions essential to junctions. From a computational viewpoint the main challenge of affordance-based individuation …

This Is The Tricky Part: When Directions Become Difficult, Stephen Hirtle, Kai-Florian Richter, Samvith Srinivas, Robert Firth

Automated route guidance systems, both web-based systems and en-route systems, have become commonplace in recent years. These systems often replace human-generated directions, which are often incomplete, vague, or in error. However, human-generated directions have the ability to differentiate between easy and complex steps through language in a way that is more difficult in automated systems. This article examines a set of human-generated verbal directions to better understand why some parts of directions are perceived as being more difficult than the remaining steps. Insights from this analysis will lead to recommendations to improve the next generation of automated route guidance systems.
